Mixed Guardrail Post Types

Question

Description Text

I have a question about the deflection of our generic guardrail.Our current standard allows the use of four different post the 6x8 wood, 8" round wood, W6x9, and W6x8.5 with a rail height at 27.75".For new construction the contractor must use the same post for the entire guardrail run.When guardrail is being repaired after a crash contractor have asked if they can mix post types.Nick Artimovich said this is fine if the deflection distances are close.Where can I get a copy of the crash test reports for the 8" round wood post or the W6x9 steel post?Thanks for your time.
